Beit known thatl, MICHAEL QU1NT, a

citizen of the United States, residing atv Another object of the invention is to provide a socket wrench having a flexible handle or stock of improved constructlon to y enable the head or socket to be applied to vnuts. in cramped or otherwise inaccessible l like.

localities.

Another object of the invention is to provide a device of this character including an adjustable socket adapted to lit a hexagonal nut from either angle to provide means whereby the wrench may be applied to the nut in cramped localities'regardless of the position of the nut.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out vin the claim, and in the drawings illustrative of the preferred embodiment of the inven-v tion. f

Fig. 5 is a transverse section on the' line 5 5 of Fig. 4.

lhe improved implement is designed more particularly for use upon nuts in cramped or otherwise inaccessible locations, and comprises a stock or handle portion 10 having means for forcible rotation, such as an eye 11 to receive a turnmg rod or the At its other end thestock 10 is enlarged as shown at 12 to provide for a semi- Fig. 3 is a transverse section on the linel y globular cavity or socket 13.

ing between the Sockets 13 and is a coupling link 16 having globular terminals 17 and 18 litting respectively in the sockets 13 and 15, as shown in Fig. 2.

The globular terminal'l' is provided with a transverse slot 19 through which a pin 2O extends and riveted or otherwise secured at lts ends ,in the walls of the enlargement 12, while the globular terminal 18 is provided with a similar transverse slot 21 through which a p in 22 extends and riveted or otherwlse secured in the adjacent walls of the intermediate coupling member 14. i

The slots 19 and 21 are preferably arranged with their longitudinal axis at angles to each other, as indicated, to increase the flexibility between the parts..

By this arrangement the three parts 10,

12 'and 14 are united by a universal or ball and socket joint, which permits a large degree of lateral adjustment of the socket portionof the improved implement.

At its lower end 23 the intermediate member 14 is ofglobular outline and lits in the cylindrical bore of a head member 24, the latter having a nut engaging socket 25 at its free end.

The globular terminal 23 is provided with a transverse aperture 26, enlarged at the ends, to receive a transverse pin 27 riveted or otherwise secured at the ends in the ad jacent walls of the member 24.

By this means the head member 24 is free Ato swing upon the pin 27 within the range of the enlarged ends of aperture 26.

The cavity 25 is designed to engage over a nut, and conforms in outline thereto, and may be formed to fit any `size or shape of nut. Y

In Fig. 4 the improved device is shown a slight modification consisting in substi tuting a square terminal 28 for the globu lar terminal 23 of the member and forming the interior or bore of the head member 24 correspondingly square to receive the same.

Formed through the squared portion 28 is an aperture 29 to receive a ball 30 and` spring 31, the ball receiving end of the aperture being restricted, as shown in Fig. 4, to hold the ball in place while at the same time permitting a portion of the ball' to protrude for engagement in socket apertures 32 in the adjacent walls of the member 24.

The `aperture 29 is closed at the end opposite to the ball by a threaded plug 33 to provide for the insertion of the ball and spring.

The socket 25 for the nut in the head 14, and partly rotated member 24 as shown in Figs. 4 and 5 is hexagonal, to engage over a hexagonal nut.

The squared portion 28 is thus held by friction only in the member 24, and can be removed b applying a pulling force applied to eit er or both of the members 24 or other of the sockets 32.

By this means the hexagonal socket 25` may be engaged with either of two positions of the nut.

It sometimes occurs that a hexagonal nut is disposed so close to a stationary part of the structure in which the bolt with which y it is engaged is placed, that the socket can understood that any and coupled with anexcept to vary the sizes and shapes of the socket 25 and head member 24.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will' be modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacricing any of its advantages.

`I claim:

An implement of the class described comprising a stock member having a semi-globular socket in one end, a nut engaging portion having a.semiglobular socket in one end, pins extending respectively through the sockets, and a link member having semi-globular terminals engaging -in said sockets, said link member having transverse slots at reverse angles to the longitudinal axis of the link and through which the pins extend.

In testimony whereof7 I alix my signature hereto.
